The shallow bowl has been identified as a brush washer in various Chinese archeological publications: see, for example, Longquan Qingci Yanjiu, 1989, illustrated drawing fig 12.4, p. 83 and plate V,3, illustrating an example excavated from a Song period tomb in the Shaoxing district.

In addition to their appearance in Chinese excavations, similar bowls were part of the Song period trade to Southeast Asia: see the Southeast Asian Ceramics Society exhibition, Chinese Celadons and Other Related Wares in Southeast Asia, Singapore, 1979, cat. nos. 68 and 69, pp. 148-149 and pl. 59, 12.5cm diameter.
